Deploying a single nationwide broadband wireless network to serve all public safety users would have great advantages over the existing fragmented public safety systems. A nationwide system could be created to serve both public safety and commercial subscribers, which would allow a provider to exploit important economies but force it to meet the more costly requirements of public safety. This paper analyzes the viability of a public-private partnership that serves public safety and commercial subscribers from a for-profit provider's perspective. A model is presented that estimates the net present value (NPV) of a wireless network by calculating costs based on the number of cell sites required and revenue based on the projected number of subscribers acquired. The model is applied to both a network that serves only commercial subscribers on 10 MHz of 700 MHz spectrum and a public-private partnership that serves commercial subscribers and public safety personnel on 20 MHz of 700 MHz spectrum. It is found that NPV is greater for the public-private partnership than for the commercial-only network for any population density, which shows that the value of 10 MHz of spectrum exceeds the cost of meeting public safety requirements. Furthermore, the paper demonstrates that NPV/cell increases with population density, so urban areas are profitable and rural areas are unprofitable. The paper demonstrates that a partnership covering 94% of the US population breaks even because the most urban 56% of population subsidizes coverage for the next 38%. If initial deployment is subsidized, a financially sustainable public-private partnership can serve much more than 94%. Additionally, it is shown that allowing urban municipalities to opt-out of the partnership can significantly increase the subsidies required.  相似文献

This article uses a case study of public recruitment in Nepal as the vehicle for a discussion of the value of three current public management models: an anticorruption model, a psychometric selection model and the new public management (NPM) model. The political context of Nepal and the role and functions of the Public Service Commission (PSC) are described. The article argues that, in contrast to current NPM doctrine, preserving the current remit of the PSC as a central agency responsible for recruitment is necessary to preserve the integrity of recruitment, which is an important element in an anticorruption strategy. The article also reviews the case for selective introduction of psychometric methods of selection. The article implies an increased importance for public recruitment in development thinking, and argues for the vital role of Service Commissions in limiting corruption. While recognizing the reality of the problems which the NPM model was developed to tackle, the article provides evidence for rejecting its claim to universality.  相似文献

Tactical choices in the design and implementation of civil service reform can determine whether it succeeds or fails. Yet researchers have paid scant attention to tactical issues in recent years. This article considers three such issues: the scope of reform, the role of aid donors, and the leadership of reform. In each area it considers what sort of approach is likely to maximize the chances of success. However, the article seeks to go beyond prescribing lessons, also looking at institutional and other reasons why reformers may be impelled to make the wrong tactical choices.  相似文献

This article explores the impact of the introduction of the New Public Management (NPM) within the UK Police Service since the mid-1990s. A specific focus upon individual performance management (one of the central features of NPM) is examined from the perspective of the police sergeant who has primary responsibility for managing performance and ultimately the delivery of policing services within one of the UK's ‘essential’ public services. After a discussion of the literature on individual performance management within the context of the NPM, the article identifies four major research questions relating to: the job role demands of performance management; access to valid and reliable performance management information; the capacity to provide follow-up development and support; and the wider integration of performance management with organization strategy and service objectives. After reporting on interview data collected from role sets in which the sergeant is a focal member, the article concludes with a discussion of the constraints upon effective performance management within the NPM.  相似文献

Abstract

This article reports the findings of a year-long research project focused on the activity of boards of directors of twenty-two trusts from the British National Health Service (NHS). The evidence gathered through the use of semi-structured interviews, focus groups, workshops, feedback questionnaires and document analysis indicates that the behavioural dynamics of boards, affected by the dominance of the expert model, act as antecedents of their statutory functions and the implementation of different governance models. Only a portion of the boards involved has effectively incorporated in its modus operandi post-New Public Management (post-NPM) principles of governance.  相似文献

In this paper, we examine the impact of public disclosure and partially informed outsiders on a risk-averse insider’s trading behavior, market efficiency, and market depth. In our model, under disclosure requirements, except for the final auction, market depth is the same at every auction. When informed outsiders are risk-neutral, in contrast to the case of a risk-averse insider with no informed outsiders, the insider is more concerned about the uncertainty about future price risk. When the number of informed outsiders increases, market liquidity improves, and the insider increases the variance of her random component to conceal her trading strategy. However, since the insider is relatively more risk-averse, she pays less attention to doing this on her own. Besides, the order flow provided by informed outsiders and randomly added by the insider injects additional liquidity into the market. When informed outsiders are risk-averse, compared to risk-neutral informed outsiders, an insider is most concerned about trading risks brought by informed outsiders at the beginning of trading. Furthermore, whether the trader is an insider or informed outsider, the more risk-averse trader has lower expected profits. Moreover, outsiders’ greater risk aversion leads to a smaller market depth.  相似文献

Book Review     
Following review of definitions of New Public Management (NPM), the paper assesses whether Canada has adopted the NPM, organized by Kernaghan and Charih's (1997) categories and using Loeffler's (1997) definition. Canada has reorganized the machinery of government, changed management methods and reduced the federal public sector substantially. Despite high debt, Canada's federal government reduced its expenditures and/or public service as much or more than the UK and New Zealand. Its expenditures as a proportion of GDP are now similar to those of the UK and New Zealand, the major proponents of NPM.  相似文献

本文在分析CES生产函数过程中引入劳动力市场,探讨了公共投资与就业的联系.本文认为,公共投资是通过劳动工资弹性来影响就业的.公共投资增加会引起劳动需求的工资弹性提高,而公共投资的溢出效应则会导致企业实际工资支出水平降低,两方面原因的共同作用引起就业的增长.在此分析基础上,本文用ARDL方法构建了一个多方程模型,并用中国的数据进行了检验.为提高分析的有效性,我们用SUR方法对模型做了系统估计,并进一步通过方程转化对变量的短期波动和长期均衡关系进行了探讨.实证研究发现,中国的公共投资增长在短期减少就业,但长期内对就业有显著的正效应.  相似文献

The religious factor in private education   总被引:1,自引:0,他引:1  
We quantify the religious factor in private education in the United States by calibrating a political economy model of school choice—among public, private-nonsectarian and subsidized religious schools—in which parents differ in their incomes and in their preferences for religious education. This shows strong latent demand for religious schooling, conditioned on current subsidized tuition levels in parochial schools, which is suppressed by the need to “pay twice” for private education. Applying the results of the calibration to gauge the effect of means-tested school voucher programs on religious and nonsectarian private enrollment, we find that when the amount of the voucher is relatively small, including subsidized religious schools in such programs is necessary for providing low-income families effective access to private education.  相似文献
